Expression to get Cumulative Count

Hi Friends, please help in writing an expression to get the cumulative count

Data has two columns one has employee name and another has leaving date. Need to plot a graph which will show month on month cumulative count for example: 10 separated in Jan, 5 in Feb and 10 in Mar. Result should show as mentioned below

Jan - 10

Feb - 15 (10+5)

Mar - 25 (15+10)

RangeCount(Above(sum(field),1,RowNo()))
